There are many interesting options on how to satisfy customers, offer appropriate services, and gain a number of financial and organizational benefits. In the case of a non-seasonal series, a naive forecast is when the last value is assumed to be equal to the next value. In recent years, machine learning, deep learning, and probabilistic programming have shown great promise in generating accurate forecasts. Reddit.

Popular classical methods that belong to this category include, (autoregressive integrated moving average), exponential smoothing methods, such as Holt-Winters, and the, , which is less widely used, but performs very well. Model-based forecasting is the strongest choice when the underlying mechanism, or physics, of the problem is known, and as such it is the right choice in many scientific and engineering situations at Uber. The prediction intervals are upper and lower forecast values that the actual value is expected to fall between with some (usually high) probability, e.g. When the underlying mechanisms are not known or are too complicated, e.g., the stock market, or not fully known, e.g., retail sales, it is usually better to apply a simple statistical model. Spatio-temporal forecasts are still an open research area. Uber Technologies isn't just a ridesharing company, and it's taking the next step to diversify its business with the introduction of grocery delivery. On the other hand, the expanding window approach uses more and more training data, while keeping the testing window size fixed. You can notice a lot of variability, but also a positive trend and weekly seasonality (e.g., December often has more peak dates because of the sheer number of major holidays scattered throughout the month). If we zoom in (Figure 3, below) and switch to hourly data for the month of July 2017, you will notice both daily and  weekly (7*24) seasonality. In fact, the Theta method won the M3 Forecasting Competition, and we also have found it to work well on Uber’s time series (moreover, it is computationally cheap). Slawek Smyl is a forecasting expert working at Uber. Subscribe to our newsletter to keep up with the latest innovations from Uber Engineering.
